· TiFeTe

TiFeTe is an intermetallic compound combining titanium, iron, and tellurium, belonging to the broader family of ternary metal compounds. This material remains primarily in the research and development phase, with potential applications in thermoelectric systems and advanced functional materials where the combination of metallic and semi-metallic character could provide useful electronic and thermal transport properties. Its industrial adoption is limited compared to established Ti alloys or Fe-based materials, making it of primary interest to materials scientists exploring novel compositions rather than mainstream engineering applications.
